Four-part webinar presented by Jacob Nadal in 2011 and 2012.

Presented by the California State Library and the California Preservation Program, this webinar will be of interest to library staff and archivists who are involved in developing digital projects, no special technical background required.

Part 1 of 4: Fundamentals

Recording of a live broadcast by Jacob Nadal that took place on December 8, 2011.

The uncertainties that go hand in hand with new technologies in digital preservation can make “once and for all” preservation approaches impractical. This first in a series of four webinars will present basic concepts and approaches to dealing with crucial digital preservation issues today and make decisions that will position you for success in the future.

Topics include storing digital objects, choosing and understanding risks in file formats, planning for migration and emulation, and the roles of metadata in digital preservation.

Part 2 of 4: Text and Image Formats

Recording of a live broadcast by Jacob Nadal that took place on January 10, 2012.

In the second part of our four-part series on Digital Preservation, this webinar will present and explain: the basic formats and standards used in digital text and digital image collections for libraries, archives, and museums; the development of text and image formats; the significant technical features that pertain to digital libraries.

Text formats and encodings introduced include ASCII, Unicode/UTF-8, and the family of standards around XML, including HTML, CSS, and EAD. Imaging topics include formats and standards, particularly TIFF, JPEG and JPEG2000, and PDF, as well as issues inherent in color management and compression.

At the end of this one-hour webinar, participants will be able to make informed decisions about text and image digitization projects and revisit their planned or existing project with an eye to making sure they will be useful sustainable into the future.

Part 3 of 4: Storing and Managing Digital Collections

Recording of a live broadcast by Jacob Nadal that took place on February 7, 2012.

In the third part of our four-part series on Digital Preservation, this webinar presents and explains: core concepts in the storage and maintenance of digital collections; how computers store data and the significant aspects of disk- and tape- based systems, including RAID arrays and “cloud” storage; basic trends in storage pricing and availability; common reference and assessment models for digital libraries, including the Open Archival Information System (OAIS) and Trusted Repository Audit and Certification (TRAC); how these technologies and standards manifest themselves in a some common digital repository and content management systems.

Participants will be able to evaluate costs and benefits of different storage methods, the applicability of repository software for their needs, and gain a framework for evaluating their immediate and hypothetical storage needs.

Part 4 of 4: Audio and Video Formats

Recording of a live broadcast by Jacob Nadal that took place on March 20, 2012.

In the last of our four-part series on Digital Preservation, this webinar present and explain: basic formats and standards used in digital audio and video collections for libraries, archives, and museums; the development of audio and video formats and introduce participants to the significant technical features that pertain to digital libraries; audio formats and encodings introduced include Pulse-Code Modulation (PCM), WAV and BWAV, and the issues related to compression for online delivery; video topics include formats and standards, particularly the role of compression and data storage; the meaning of “HD” and options for video transfer and capture, as well as format and encodings for uncompressed video and the Motion JPEG standards.

Participants in this webinar will be able to make informed decisions about digital audio and video projects and revisit their planned or existing projects with an eye to making sure they will be useful sustainable into the future.
